OTher than the water seperator. Where are any fuel filters or screens on a 97 454 mag mpi's. I am so lucky to have the VST's too.. Any help would be helpful.. Thanks

Mine came with two inline filters mounted on the transom, one from each tank. The fuel pump in the VST tank has a filter on the input of it, that can be changed but you will probably need a new o-ring seal kit, and while you are in there replace the vent diapgram. If you are not having problems I wouldn't mess with it. If you are having problems, I would take the effort to replace the setup. I fired a piston last year due to the lift pump failing and leaned it out. I do have the old VST tank that I would get ride of if you need one!

The parts are expensive and being discontiued.
